Thermal Conductivity

Typical thermal-conductivity figures from the FRF Pipe Datasheet are shown below.

Mean Temperature	100 kg/m³	140–150 kg/m³
24°C	0.033 W/mK	0.032 W/mK
35°C	0.035 W/mK	0.033 W/mK
50°C	0.037 W/mK	0.035 W/mK
100°C	0.044 W/mK	0.041 W/mK
150°C	0.052 W/mK	0.048 W/mK
200°C	0.061 W/mK	0.056 W/mK
250°C	0.072 W/mK	0.065 W/mK
300°C	0.084 W/mK	0.078 W/mK

FRF states that these are typical values and are subject to normal manufacturing and testing variance. The thermal-conductivity values are shown in accordance with ASTM C335.

Service Temperature

FRF Rockwool Pipe insulation has a stated service temperature of 780°C when tested in accordance with DIN 52271 at 80 mm thickness and 100 kg/m³ density.

FRF also states that its Rockwool fibres can withstand temperatures above 1000°C without melting. When temperatures exceed 250°C, the binder may evaporate in the exposed zone, while the Rockwool fibres remain intact.

Fire and Material Properties

FRF Pipe Sections are described as non-combustible when tested in accordance with relevant fire-performance standards including:

• BS 476 Part 4
• ASTM E136
• BS EN ISO 1182

FRF documentation also reports reaction-to-fire performance as Class A1 under BS EN 13501-1.

Use the current FRF technical documentation when confirming project-specific fire-performance requirements.

Stainless-Steel Compatibility

FRF documentation states that the insulation meets the requirements of ASTM C795, the standard specification for thermal insulation used in contact with austenitic stainless steel.

Testing references include:

• ASTM C692 – Corrosion Test
• ASTM C871 – Chemical Analysis

Installation – Banding

FRF recommends securing Pipe Sections using suitable banding.

The datasheet recommends:

• Three steel bands per pipe-section length
• Band positions approximately 100 mm from the lateral joints
• Wire ties or spiral binding may be used where appropriate for pipe sections with an outer diameter of 200 mm or less

Source: FRF Rockwool Pipe Datasheet, April 2018.

Multi-Layer Installation

Where more than one insulation layer is required:

• Both insulation layers should be banded.
• Outer-layer joints should be staggered both laterally and longitudinally.
• For insulation thickness above 100 mm or operating temperatures above 250°C, FRF recommends installation in two layers.

Installation Recommendations

Before installation:

• Ensure all contact surfaces are clean, dry and free from dust.
• Use suitable protective equipment when handling the insulation.
• Fit the preformed pipe sections closely around the pipe.
• Position the longitudinal joint towards the lower side of the pipe.
• Stagger longitudinal joints by at least 30°.
• Secure the insulation with suitable binding wire/banding.

For multi-layer installations, stagger both longitudinal and crosswise joints.

Cold Pipework

For cold-service pipework, the insulation system should include a continuous vapour retarder to reduce the risk of vapour ingress and condensation.

The vapour-retarder system, joints, penetrations and external finish should be selected according to the project specification and operating conditions.
